The significance of the transition of the triplet transition can be quantified by using the \(z\) -score (standard score). The \(z\) -score has been used to a qualitative measure of statistical significance of different motifs [1]} or temporal motifs [2]}. We apply similar procedures to compute \(z\) -scores for different triplet transitions and for a transition from graphlet \(m_i\)  to graphlet \(m_j\)  we define
\(Z_{ij}= \frac{ \langle  \widehat{\mathsf {T}}_{ij}(s)  \rangle  - \langle  \widehat{\mathsf {T}}^{\mathrm {(pw)}}_{ij}(s)  \rangle  }{ \sigma ^{\mathrm {(pw)}}_{ij} } \, .\)
